How far will Russian President Vladimir Putin go to win his war in Ukraine?
The question looms larger and more worrying as the invasion slows and his dreams of conquest are put on hold. His mounting frustration has prompted fears that Putin is willing to use weapons of mass destruction (WMD) to prevail.
While Putin has issued nuclear threats, the real danger appears to be a readiness to use chemical or biological weapons. Russian officials have launched a disinformation campaign that seems to lay the groundwork for the deployment of bioweapons.
